SPECIFICATION forming part of Letters Patent No. 276,647, dated May 1, 1883. i Application filed March 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, EDWIN STANTON THUR- BER, of Boston, in the county ot Suiolk, ot' the Commonwealth of Massachusetts, have invented a new and useful Improvement in Horseshoes; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of whichy Figure 1 is a top view, Fig. 2 a bottom view, Fig. 3 a front elevation, Fig. 4 a longitudinal and vertical section, Fig. 5 a side view, and Fig. Ga horizontal section, of a horseshoe 'provided with my invention, the nature of which is defined in the claims hereinafter presented. Fig. 7 is a side view of one of the calks.

The said invention is for securing the toe and heel calks to the slice, and to render them easily' removable therefrom and others put in their places, as occasion may require. For this purpose each ot' the said calks isnot only furnished with a dovetailed tcnou to extend from it into a corresponding inortise made in the shoe, buthas a passage or hole made through such tenbn to receive a wire which goes through 4such pssage or hole and in a groove made in groove, b,which opens into each mortise. Each calk B has a dovetailed tenon, c, extending .from its upper end and adapted to fit the mortise in the shoe, and through such tenoln transversely, and near its outer or smaller side, is a passage or hole, d, to receive a wire, G, which is placed around the shoe and in the groove and goes through thel calli-tenons. The groove holds thewire in place, and it and the wire operate to secure the calks to the shoe. The wire, at each end, may be bent at a right angle and either extended into the shoe or lapped on its heels.

When the calks maybecome Worn so as to beot little or no usethey can easilyT he extracted from the shoe at'ter removal of the wire from itA and them, and others or unworn ones of like construction may he substituted.

I claim- 1.4 The horseshoe grooved and mortised, substautiallyas described, for reception ot'a wire and calks, as explained.

2.-,The horseshoe having a groove and dovetailed mortises arranged in it, substantially as described, in combination with calks provided with dovetailed tenons to iit the mortises, and with a wire arranged in the groove and ex tended through such` tenons, all being essentially as explained.
